MACHINE FOR PACKING STARCI-I, 85C.

Specification of Letters Patent No. 26,084, dated November 15, 1859.

To aZZ 'whom 'it may concern:

Be it known that I, ISAAC A. BRowNnLL, of Providence, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Machinery for Packing in Bundles or PackagesCommodities of the Nature of Starch, Saleratus, Farina, &c.; and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,in which Figure l, is a plan of the machine. Fig. Fig. 3, is a sectionthrough the line A, A of Fig. l. Fig. t, Nos. l, 2, 3, 4, 5, 6, 7,represent the different stages of the operation.

Similar letters refer to like parts in the different figures.

B, B, is the frame of the machine of wood surmounted by a table C, alsoof wood, from which ascend the columns o, b, o, o, of cast iron whichform a support for the spider c, c, which is secured to the columnsl inits proper position by bolts passing through the same into the frame.The hub (Z, of this spider forms the upper bearing for the verticalshaft D, which has a bearing also at the bottom in the step E.

Uppermost upon the shaft is the wheel F, having two rims f, f', fastenedtogether by the studs e, c, e, &c, and suitable bolts passing throughthe saine, or in any other convenient manner. This wheel turns looselyupon the vertical shaft, and is held in its.

proper position thereon by the collar g. In the rims of this wheel areformed apertures of corresponding size and form (square) sixteen innumber, (though more or less may be employed according to the size ofthe machine or its capacity,) in which slide suitable square blocks of,from two to three inches diameter by eighteen (18) inches long of woodZ1., ZL, on the top of which are placed the cans z', z', z' &c. formedof sheet iron and firmly riveted to the casting at' the base which takesin the top of the block and is firmly secured thereon by screws orotherwise.

Within the can is a plate of metal y', to which is attached the rod y',extending downward inside the block which is formed to receive it (asshown in Fig. 3) this plate is made to slide within the can verticallyfor purposes hereinafter explained. The'blocks are shod at the bottomwith a plate of hammered leather or hide toprevent splitting. Attachedto the blocks also are two studs Z, Z, &cr, r, r, &c one Z, Z, upon theVinside midway between the two rims of the wheel F, and the other uponthe outside near the bottom (r, 1 &c) these are cut into the wood andsecured by screws. Lower down upon the shaft (D) is secured thecam-wheel Gr, which is made fast to the shaft by set screws in the hub.Upon the periphery of this wheel are secured cams or wedges t, t, z? &c,sixteen in number (or one to each block). These by the revolving of thewheel are made to lift the blocks, (by passing beneath the studs Z, Z,&c.) to a proper height and drop the same in a continuous motion. Theyare so arranged upon the wheel with relation` to each other, as torender the resistance caused by friction upon their surface, equalduring the entire revolution. This is accomplished by varying theposition of each one additional sixteenth from the preceding one fromsixteen equal divisions of the wheels rim (or circumference).

H, H, is a ring of cast iron secured by the feet K, K, &c to the frameby suitable bolts as shown, this ring is turned smooth upon its uppersurface and serves as a solid foundation or table for the continuoushammering of the blocks. Secured upon the outer edge of the ring is arail a, a, extending around the same a little more than a quarter of thecircumferenceand terminating at each end at a', a2, in an inclinedplane. The studs r, r, &c in their turn ride up the inclined end of thisrail at a and in so doing lift the inner studs Z, Z, &c from contactwithv the cams thereby depriving the blocks of their jolting motion.Five blocks remain at rest in this way, at one time, during which onebundle is withdrawn from the can, an empty bag inserted in its place,and an additional portion of the commodity supplied to the bag in thecan which is about to descend from the rail at a2, to take its placewith those in motion.

Through the rinO II, and directly beneath the center of tblock No. l, isa rod or punch S. This moves vertically in guides at 79, p, and isconnected with the foot-lever u, by the rod v, at the lower end of thepunch is fastened a weight, that it may quickly and surely descend. whenreleased by the foot of the operator. Attached to the rod S is the hubwhich slides loosely upon the rod y, which is provided at the bottomwith a nut and a washer of leather. Upon the outside of this ring is thestop o, secured in its proper position (as shown in Fig. 3) the studs1", r &c stop directly beneath the projecting top of the same, therebypreventing the blocks from rising while the completed bundles are beingforced from the can.

Opposite upon the inside edge of the ring is secured a casting in whichis formed a barrel or recess for a spiral spring acting upon the latchor pawl w, Apressing the same upward against the lower rib m, or uponthe rim f of wheel F, and into the notches cut therein opposite thecenters of the blocks, and by means of which the wheel is prevented fromturning, while the commodity is being introduced; and the completedbundle is being withdrawn from the cans. It is released when desired, bylifting the end of the lever u, with the foot.

Motion is communicated to the shafts I), through the medium of the bevelwheels M and N, the shaft P and the pulleys R, R.

The commodity is supplied to the bags through the tunnel T, (Figs. 4,No. 3) which is so constructed that the commodity will readily dischargeitself into the bag in a stream or jet (from the nozzle Z, at thebottom), of about one-third the diameter of the bag. Upon the outside isa nozzle a A which fills the entire mouth of the bag and is secured tothe outside of the tunnel by the ring V, which is pierced with holes tofurnish an escape for the air while the commodity is being introduced,(as shown by the arrows in the figure).

Operation: In Fig. 1, an operative stands at the position indicated byW, and one also at V. I, is a pot of glue for sealing the packages. J,represents the scale for weighing the commodity. The machine is set inmotion and the revolving cam-wheel is continually jolting eleven of thecans (occupying the position of numbers 6, 7, 8, 9, 10, 11, 12,13, 14,15, 16,) while five (in the position of numbers l, 2, 3, 4, 5, remain atrest. The wheel F, remains stationary with the shaft D, turning in itshub. WV, places a bag in can No. 1 and raises with his foot the lever u,when, the weight of the blocks acting as a resistance upon the face ofthe cams, the motion of the cam wheel is communicated, by the frictionthus created, to the wheel F, which brings can No. 2 up to receive anempty bag, Fig. 4, No. 2. This operation is repeated until can No. 1,stands opposite operative V, in the position of Fig. 5, Fig. 1, whohaving weighed the proper portion of the commodity lls the same into thebag through the tunnelas shown the center of the bottom of the bag andslides each way against the sides thereof and in so filling graduallyeXpels the air which escapes (in the direction shown by the arrows)between the inside nozzle Z, and the outside nozzle A, throughperforations in the ring at the top of the latter. The tunnel is thenremoved (Fig. 4, No. 4), the wheel F is released and the block slidesdown the incline at a2, and takes its place at No. 6, another bag issupplied by W, and another quantity is weighed and filled into can No. 2by V, during which time thecam wheel has made one and a half (125)revolutions thereby giving can No. 1 twenty-four (24) jolts or drops.Can No. 2 is now set in motion and the operation continues until can No.1 arrives opposite operative W. It has at this stage received 24 11=264,two hundred and sixty-four successive jolts or drops,

^ and is reduced in bulk (as shown in Fig. 4,

No. 5). The end e of the bag is then folded by V, glue applied and asquare piece of paper or label Q, (Fig. 4 No. 1) is pressed upon the endof the bundle, when the latter presents the appearance as is representedin Fig. 4 No. 6. Operative V, then steps upon the lever u, when thepunch S, is forced up.

against the rod y', thereby forcing the completed bundle from the can(Fig. 4 No. 7). The foot is then suddenly removed from the lever (u)when the punch (S) descends with sufficient force to jerk the pawl 'wfrom the notch in the rim of the wheel F, through y the medium of therod y, and the hub thereby liberating the wheel and causing can No. 2,to assume the position and to be similarly operated upon with thepreceding one. Thus the operation continues-the part to be performed byhand being about equally divided between the two operatives.

I do not claim broadly a tunnel with a surrounding air escape applied tothe nozzle, but restrict myself to a tunnel of such construction as anauxiliary device requisite to the successful performance of the otheroperations of my machine.

I claim- 1. The tunnel T, as constructed for the purpose substantiallyas herein above described.

2. I claim attaching the cans z', i to upright strips of wood or metalwhich receive, and transmit to the said cans the motions which reduce inbulk the commodity placed therein.

3. I claim the wheel F or its equivalent for holding and carrying theblocks L, 71 in combination with the cam-wheel Gr or its equivalent andthe studs Z, Z, &c. for imparting the motions which reduce the commodityin bulk, and also the intermitting Arotary motion to the wheel F, forthe purlever u, the rod o, and the punch S, with the motion in themanner and for the purpose rod and plate y', for the purpose speciied.specified.

I also claim in combination With the punch S, the paWl w, rod 3/ andsliding hub m for ISAAC A' BROVVNELL l 5 liberating the Wheel F, at theproper time. Witnesses: 5. I claim the rail a, a, and the studs A. K.OsBoRN,

7', 7, &c. With the stop o, for Withholding WV. OSBORN.
